Description

Technical Field

[0001] The utility model relates to fruit picking equipment, in particular to a structural improvement of a vibration type fruit picking machine. Background Art

[0002] The use of vibrating fruit pickers has brought great convenience to the harvesting of fruits of plants such as pine cones, walnuts, and chestnuts. It not only improves the efficiency of fruit harvesting, but also saves labor expenses. The Chinese utility model patent with publication number CN217608408U discloses a technical solution of a "vibrating pine cone picker". It uses a pair of meshing eccentric gears as a vibration source to output vibration, and has a good use effect. However, due to the use of a pair of eccentric gear meshing transmission, the two eccentric gears are distributed on different rotating shafts, occupying a large vertical space, making it difficult to further reduce its size and weight under the premise of unchanged output power. This makes it even more difficult to carry a picker through the woodland, which is already difficult to travel. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a vibration-type fruit picking machine with a more compact structure.

[0004] The technical solution of the utility model is: a vibration-type fruit picking machine, comprising a casing, a vibration device and a driving device, the casing is provided with abutting part, the vibration device comprises an eccentric wheel and a driving gear, there are three eccentric wheels, the three eccentric wheels are coaxially arranged on the eccentric wheel shaft, the eccentric wheels on both sides are provided with teeth on the wheel rim and are rotatably connected to the eccentric wheel shaft, the other two eccentric wheels are fixedly connected to the eccentric wheel shaft, and at least one of the two eccentric wheels is provided with teeth on the wheel rim, there are two driving gears, the two driving gears are meshed with each other, and are respectively meshed with the middle eccentric wheel and another eccentric wheel with teeth on the wheel rim, and one of the driving gears is connected to the driving device through the driving wheel shaft.

[0005] The technical effect of the utility model is that it has the advantages of reasonable structural design, compact size, lighter weight, and easy to carry and transport. The eccentric gear coaxial structural design is adopted, so that the larger gears are arranged coaxially together, which greatly reduces the size and weight of the whole machine. In particular, the reduction in vertical size makes it easier to tie the fuselage to uneven or short tree trunks. The whole machine is light in weight and adopts a combination structure of three parts, namely, a vibration device, a tree trunk abutment part and a driving device, which can be easily disassembled. It can be carried by one person or disassembled and distributed to multiple people to carry, further improving the convenience of long-distance transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 2 It is a structural schematic diagram of the vibration device part of the utility model. DETAILED DESCRIPTION

[0008] like Figures 1 to 2 As shown, the vibrating fruit picking machine includes a casing 1, a vibrating device and a driving device. The casing 1 is provided with a supporting portion 2 for connecting to a tree trunk. The vibrating device generates a vibration force by an eccentric wheel (eccentric block or eccentric weight). The vibrating device includes an eccentric wheel 3 and a driving gear 4. There are three eccentric wheels 3, and the diameters of the three eccentric wheels are equivalent. The three eccentric wheels 3 are coaxially arranged on an eccentric wheel shaft 5. The middle eccentric wheel 3 is provided with teeth on the rim and is rotatably connected to the eccentric wheel shaft 5 through a bearing. The other two eccentric wheels 3 on both sides are fixedly connected to the eccentric wheel shaft 5 and rotate with the eccentric wheel shaft, and at least one of the two eccentric wheels is provided with teeth on the rim. There are two driving gears 4, and the two driving gears 4 are meshed with each other and respectively meshed with the middle eccentric wheel 3 and the other eccentric wheel 3 with teeth on the rim. The two driving gears are wide-toothed, and the meshed parts overlap each other. The parts on both sides are respectively meshed with an eccentric wheel, and one of the driving gears 4 is connected to the driving device through a driving wheel shaft 6. The driving device drives a driving gear to rotate, and the other meshing driving gear rotates in the opposite direction at the same time, driving the three eccentric wheels to rotate together. When the three eccentric wheels rotate, the middle eccentric wheel rotates in one direction, while the other two eccentric wheels on both sides rotate in the opposite direction. This scheme adopts the eccentric wheel method, that is, the counterweight is directly set on the wheel to form an eccentric wheel. The counterweight is directly set on the eccentric wheel, which can make the structure more compact and smaller in size. The counterweight is reasonably distributed to the three eccentric wheels after calculation, so that the machine body generates lateral amplitude when vibrating, and the longitudinal amplitude is offset by the reverse force generated by the counterweight. The driving device can be driven by a single-cylinder gasoline engine, such as the engine used in ordinary chain saws, which has the advantages of small size, light weight and easy to move and transport.

[0009] The housing 1 and the abutting part 2 are split structures, and the housing 1 and the abutting part 2 are detachably connected. A tightening wire for tying the picker to the tree is arranged on the abutting part. When in use, the abutting part is first used as a fixed base, and is tied and fixed to the tree trunk through the tightening wire. Then the vibration device is connected to the abutting part to complete the picking operation. The advantage of the split setting is that it is convenient for multiple people to carry, share the weight, and reduce the personal load.

[0010] The housing 1 and the abutting portion 2 are connected by bolts.

[0011] The side where the housing 1 is connected to the abutting part is provided with a slot 7 near one end, and a latch 8 corresponding to the slot 7 is fixed at the corresponding position of the abutting part 2. The housing 1 and the abutting part 2 are connected at this end through the slot 7 and the latch 8, and the other end of the housing 1 and the abutting part 2 is provided with a bolt hole and connected by bolts. The connecting bolts can also be replaced by other quick connectors to improve assembly efficiency. However, the reliability of the connection needs to be ensured to avoid the phenomenon of loosening of parts due to vibration.

[0012] The driving gear 4 is connected to the driving device via a spline. Splines and spline grooves are respectively arranged on the driving gear axle and the output shaft of the driving device to achieve connection.

[0013] The driving device is detachably connected to the housing 1 .

[0014] The housing 1 is provided with a drive device connection seat 9 and connection bolts, and the drive device and the housing 1 are connected at the drive device connection seat 9 by bolts.
